This 3D model was originally created with Sketchup 8 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 5MB. I think I made a mistake. I located it in Philadelphia, main hub. It has a pilot storage, where I too made a mistake, main building, 4 hangars, several airstars, a blank plane by 50210, and some jetways. Airstairs and jetways are just for being owned for test flights. It also has a runway. Also the second main hub.
